+ * LangPackMatcher.jsm calls out to to the addons store, which involves network requests.
+ * Other tests create a fake addons server, and install mock XPIs. At the time of this
+ * writing that infrastructure is not available for mochitests.
+ *
+ * Instead, this test mocks out APIs that have a side-effect, so the addons of the browser
+ * are never modified.
+ *
+ * The calls to get the app's locale and system's locale are also mocked so that the
+ * different language mismatch scenarios can be run through.
+ *
+ * The locales are BCP 47 identifiers:
+ *
+ * @param {{
+ *   sandbox: SinonSandbox,
+ *   systemLocale: string,
+ *   appLocale, string,
+ * }}
